GeForce GTX 480 vs Radeon RX 6500 XT

Intro

Compare that to the Radeon RX 6500 XT, which has a core clock speed of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 64-bit memory bus, and makes use of a 6 nm design. It is made up of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 480		250 Watts
	Difference: 143 Watts (134%)

Memory Bandwidth

In theory, the GeForce GTX 480 will be 20% quicker than the Radeon RX 6500 XT in general, because of its greater data rate. (explain)

GeForce GTX 480		177408 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 29952 (20%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 235%) faster with regards to texture filtering than the GeForce GTX 480. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 98800 (235%)

Pixel Rate

The Radeon RX 6500 XT is a lot (about 110%) more effective at full screen anti-aliasing than the GeForce GTX 480, and capable of handling higher resolutions better. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 480		33600 Mpixels/sec
	Difference: 36800 (110%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
